Product Detail

Welcome to the GoatStrada cat-back exhaust system for the F87 M2C platform, or in other words, the solution to the S55 sound problem. For years enthusiasts have wanted to find a solution to the buzzy and raspy sound these cars produce from the factory. As the M2 Competition has the same problem as its big brother, we had to develop a solution for it. Our mission has been to find this hidden sound and allow all F87C owners to enjoy it. This full catback is comprised of a 2.75" equal length mid section with an H pipe configuration. After traveling through the H pipe the exhaust is combined into a 3.5-inch axle back. This combination helps smooth the exhaust tones to provide a very enjoyable sound through the entire rev range. When operating with the valves open, the exhaust gases exit unrestricted out of the passenger side exhaust tips. With the valves closed the exhaust passes through our quad chambered muffler and out of the drivers side exhaust tips for a lower volume experience, very well suited to daily driving and not alerting the Karens. This system mounts up to factory mounting points and is a direct bolt-on. It's time to make your M2 Competition sound like it always should have.

Some custom exhausts and one-off mufflers for vehicles subject to acceleration noise regulations are not compatible with vehicle inspections and are not guaranteed for use on public roads.

Like products from other manufacturers, exhaust parts are consumables and require regular maintenance, exhaust leak checks, and wire insulation treatments. We are not responsible for any damage, vehicle damage, accidents, fires, or any other troubles that occur during use. Please consider this at your own risk.

FRP products are delivered in their raw state, so basic putty treatment is necessary. Due to the manufacturing process, some carbon front lips and rear diffusers may have carbon seams. There may also be occasional inconsistencies, bubbles, or blemishes in the clear coat of carbon parts. Although we take the utmost care to inspect for these issues, any overlooked items must be handled by the customer. Transportation accidents or damage are generally not covered by our warranty and are dependent on the logistics company's response.

Some exterior parts, including body kits, may be installable as-is, while others, similar to other manufacturers, may require modifications. Please consider that some parts may require cutting, trimming, or other adjustments. In such cases, we do not accept returns or refunds. We ask for your understanding and request that customers who are particular, or expect dry carbon quality from wet carbon, or seek perfect quality, refrain from purchasing.
